Cycle Function - Siemens 7LF4 531-0 Operating Instructions Manual

Cycle function

Only available in EXPERT mode
For cyclical switch commands the switching on time is set by logical "OR" of programs of all types. A fixed cycle of ON and OFF time then operates within those
limits. The cycle always starts with the ON time. The cycle duration and the ON time within the cycle have the same length for all switching times. The cycle
duration and the ON time can be set independently in one-second increments. If the switching time is shorter than the cycle duration, the cycle will be shortened
accordingly. The ON time will remain unchanged. If the switching time is actually shorter than the ON time, the ON time will be shortened accordingly.

Control input with delay time
A control signal is superimposed on all program commands. While this control signal is applied, the output is switched ON.
When the control signal is switched off, the output is switched OFF after a delay time, unless an ON command is applied by a program.
